Revision history [back]

My idea is the following:

• Fill the "hollow circles" in the binary image: using the negative of the first image in post, make a connected component analysis. The first connected component is the background, the others are the isolated areas inside the blood cells.

  Set these areas to 255 on the original binarized image. So you'll have a well segmented image.

• Compute the distance transform on this binary image. Use the maxima to detect the blood cellls.
